286. micro-elution In the context of SPE, media that feature lower sorbent weight and specialized design compared with traditional SPE, allowing reduced elution volumes while maintaining recovery and performance.
287. microbore column A chromatographic column with an inner diameter comprising between 1 and 2.1 mm and operated at mobile phase flow rates between 50 and 1000 μl/min. This configuration could provide increased detection sensitivity and it is attractive for the analysis of low-volume (or low-concentration) samples.
288. microflow A liquid chromatographic method employing a mobile phase with a low flow rate, typically 1–50 µl/min.
289. microfluidics A field of technology using systems in which very small volumes of fluids are handled. For bioanalysis, this term usually refers to miniaturized devices that contain small flow channels and that combine one or multiple analytical functions in a single device. Also known as ‘lab-on-a-chip’.
